companying drawings.

With the above and other objects in. view, the invention conslsts 1n the novel features of construction and the combination and arrangement of parts hereinatter more fully described, pointed. out in the claim and shown in the acornpanying drawings, in Wl'1lCl1:

Figure 1 IS a vertical sectional View; Fig.

2 is a sectional view on the line 2---2 of Fig. i

1; Fig. 3 is an enlarged detail sectional view. Fig. 4 is a section on the line l l of Fig. 1.

Referring more particularly to the drawings 1 indicates the casing which is prof: erably rectangular in shape and made from heavy sheet metal or any other desired ma terial. Centrally arrahg'ed in this casing; is a U-shaped gear housing 2 securely fastened therein by means of the rivets 3 passingthrough the bottom of the housing and through the back side of the casing,,said housing having flanges 4- tormed on each end and riveted to the top and bottom of the casing.

Disposed between the outer walls of the casing and the gear housing are the/brace bars 5 having their ends bent at right, angles and securely fastened by means of the rivets 6. Mounted in the lower end of the casing is the main shaft 7 upon which is mounted the springs 8, said springs having their inner ends secured to the shaft and their outer'ends secured to the circular springicasings 9. Mounted on the shaft '3' I ai'liaccnt said spring); casings are the winding gears 10 operated hv ineaiiis of the small cogs 11 mounted on the erunlc 12, said crank shafts being provided with handles on the outside of the casing lio operate said winding gears and wind up said springs. Ratchet \vl'iocls 123 are mounted on the shaft 7 adi-acoi'lt the girars it] and pawls 1-1! are ,mounted on the pins 15 and adapted to engage said ratchet wheels to prevent;

backward movement of the winding gears; H (Jnc end of tho spring musings f) is provided with a reijluccd alocvc it; which is discasing.

Disposed in the casing above one of the station's 8 and mounted between two of the brace bars 5 is a governor 23, said governor having its lower end lccycd to the shaft 24: and the upper end is provided with an inn wardly extending sleeve which is loosely mounted on said shat't. A gear E26 is monnted on the upper end oi" said shaft and adapted to mesh with the gcarfi'i on the operating shaft. 4 1

A disk 28 is mounted on the upper end of the governor and a regu ator is mounted on one of the brace lllll'n' 5 and iliaposed adjacent said dislqoaid regulator comprising a rod 21) mounted in said brace hur, having its upper end screw threaded and a winged nut 30 is mounted thcri'eou. The lower end of said rod is bent twice at rightanglcs and a friction tip 31. is placed on the upwardly extending end of the bent portion of the rod to engage the lower face of the disk 28 and regulate the speed of the governor. Al coil spring 32 is mounted on said rod and disposed between the bracket 33' and the lower endozt the rod so that when the nut 30 is turned to release the {governor the spring will expand and force the tip 31 away from the dish and thus it will be seen that. by the turning of the winged nut 30 the. governor can be regulated to run fast or s ow.

Aily wheel is mountedon one endof 11 of said shaft are two arms 38 replaced by a gear okany other desired means.

A starting and stop device is provided which comprises a vertically disposed shaft 36 having one end disposed through the upper sidcof the casing and a hand wheel 37 threaded thereon. Formed on the lower end extending at right r angles therefrom and their outer ends with the friction tips 39 adapted to engage the lower face of the disk 28. A coil spring 40 ismounted on the lower end of the shaft and disposed between the brace bar 5 and the arms 38. so that when the wheel 37is turned to release the governor the spring willexpand and force the tips 39 away from the disk 28 allowing the governor to rotate.

In construetingmy improved motor the gears 19 and 21 may be replaced by pulleys if so desired and the train of gears 20 may be replaced by a belt to connect. said gears.

It Will be obvious that when the springs 8 are Wound up and the governor is released the springs Wlll turn the casing 9 which in turn will rotate the gear 19 and impart motion to the operatingshaft. 22 by means of that-rain of gears 20, the speed of said operating shaftbeing regulated by the governor 23.

' While I have shown anddescribed the preferred'form of my invention it will be obvious that various changes in the details provided 011' means oi" Witnesses:

of construction and in the proportion may be resorted to for successfully carryingmy invention into practice-withoi-lt sacrificing .any of the novel features or departing front the scope thereof.

Having thus described the invention what is claimed is A springmotor comprising a casing, a U shaped gear housing centrally arranged and secured therein, a shaft mounted in the lower s end of said casing,

mounted on said shaft and arranged upon each side of the housing, springs arranged in said casings and having one end secured thereto and the other ehd secured to the shaft, inwardly extending reduced sleeves formed on said casings, a gear Wheelmounted on said shaft, annular flanges formed on the inner ends of said sleeves and adapted circular spring casings to be secured to the gear Wheel, an operating shaft mounted in the upper end of the first casings, means for connecting said gear wheel with the operating shaft, means for placing the said springs under tension for.

rotating said casings and imparting motion to the operatingshaft, and means-for regulating the speed of said operating shaft.

In testimony whereof I hereunto atlix my signature in the presence of two Witnesses.
